android.os.FileUriExposedException: file:///storage/emulated/0/vcf_demonuts/android_1633671182515.vcf exposed beyond app through Intent.getData()

MY Code

            var vdfdirectory = File(
                Environment.getExternalStorageDirectory().toString()   VCF_DIRECTORY
            );
            // have the object build the directory structure, if needed.
            if (!vdfdirectory.exists()) {
                vdfdirectory.mkdirs();
            }

            vcfFile =
                File(vdfdirectory, "android_"   Calendar.getInstance().getTimeInMillis()   ".vcf");

            val fw: FileWriter = FileWriter(vcfFile);
            fw.write("BEGIN:VCARD\r\n");
            fw.write("VERSION:3.0\r\n");
            // fw.write("N:"   p.getSurname()   ";"   p.getFirstName()   "\r\n");
            fw.write("FN:"   "Sibtain"   "\r\n");
            //  fw.write("ORG:"   p.getCompanyName()   "\r\n");
            //  fw.write("TITLE:"   p.getTitle()   "\r\n");
            fw.write("TEL;TYPE=WORK,VOICE:"   " 923155022905"   "\r\n");
            //   fw.write("TEL;TYPE=HOME,VOICE:"   p.getHomePhone()   "\r\n");

            fw.close();


            val txtIntent = Intent(Intent.ACTION_SEND)
            txtIntent.setDataAndType(Uri.fromFile(vcfFile), "text/x-vcard");
            startActivity(Intent.createChooser(txtIntent, "Share"))
            Toast.makeText(this, "Created!", Toast.LENGTH_SHORT).show();

*I have Try following&solution available on stackoverflow

I have create provider_path.xml file

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths> 

Manifest

<provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="com.example.testapp.provider"
            android:exported="false"
            android:grantUriPermissions="true"
            tools:replace="android:authorities">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"
                tools:replace="android:resource" />
        </provider> 

CodePudding user response：

In the onCreate method your application file. Place the following code

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());

This will make the exception go away. However, this is used mostly as a diagnostic tool and it not a proper solution.

Another solution with the fileProvider method would be to add FLAG_GRANT_READ_URI_PERMISSION flag to your intent.

Intent intent = new Intent(Intent.ACTION_VIEW, FileProvider.getUriForFile(this, AUTHORITY, f));
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);

Try below code it works for sharing VCFile:

 private void shareContact(ContactsModal modal) {

    String lookupKey = null;
    Cursor cur = ((Activity)context).getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, new String[]
            { ContactsContract.Contacts.LOOKUP_KEY },
            ContactsContract.Contacts._ID   " = "   modal.getContactID(), null, null);

    if (cur.moveToFirst()) {
         lookupKey = cur.getString(0);
    }
    if(lookupKey!=null){
        Uri vcardUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType(ContactsContract.Contacts.CONTENT_VCARD_TYPE);
        intent.putExtra(Intent.EXTRA_STREAM, vcardUri);
        intent.putExtra(Intent.EXTRA_SUBJECT, "Contact Name");
        ((Activity)context).startActivity(intent);
    }
}
